The system carries an open license (modeled on that for Princeton WordNet), which allows all manner of applications, including commercial use.

The new version describes over 106000 unique lemmas (and over 160000 lexical units), interlinked by over twenty semantic relations. The download includes the latest results of the mapping of plWordNet 2.0 onto Princeton WordNet 3.0 (over 39 000 Polish synsets). They cover the following categories: person, artefact, location, food, time, state and process (partially), economic vocabulary (partially), communication (partially).

The system can be downloaded in the native plwnXML format and in the Princeton WordNet format. Part of the data is also available in the VisDic format.
